Description
Metric Male 24° Cone / BSP 60° Cone Seal – Dual Standard Hydraulic Transition Fitting
Product Overview
The Metric Male 24° Cone / BSP 60° Cone Seal is a specialized hydraulic transition fitting designed to bridge Metric and British Standard Pipe (BSP) thread systems. This unique adapter combines DIN 24° cone sealing (ISO 8434-1) with BSP 60° taper thread sealing, making it an essential component for international hydraulic systems requiring cross-standard compatibility.
Key differentiators from previous products:
- Dual-standard design: Seamlessly connects Metric (M12×1.5 to M52×2) and BSP (G1/8″ to G1-1/2″) threads
- No O-ring required: Relies on precision metal-to-metal cone sealing for both interfaces
- Higher pressure rating: Optimized design withstands up to 50 MPa (7250 psi)
